I have a sheet that toggles hidden values of certain rows and columns
to accommodate the views of data for different users.
Trouble is, in addition to this, some rows are permanently hidden as
once they are too old - but not deleted to keep as reference.
In each of the views, position of the freeze panes is different.
Always in the same position in the eyes of the user, but a different
cell every time an old row becomes hidden.

In a nutshell, with a sheet with unknown hidden rows/columns, how
could you pinpoint position (5,4) according to what you see, not what
is both shown and hidden?

thanks in advance and I hope that is clear enough
